To all whom/it 'may concern.' '.--Y

Be it known that I, FRANK P. SNOW, a

.citizen of theUnited States, residing at' Los Angeles, in the county ofLosAngeles and State of California, have invented certain t newand'useful Improvements in Irrigatin Valves, of which the following is aspecication.

This invention relates to improvements in valve mechanisms andVespecially to a valve vwhich is adapted for use upon the ends'of standpipes or in other places where it is desired to control the outflow ofwater or other --material'from a pipe or other duct.

It is an object of the invention to yprovide a valve which is carried-byafremovable support 'adapted to be held in a duct or stand pipe or'other channel way for controlling the movement of water and othermaterials.

' It is also an object of the invention to p'rovide` 'a valvesuitablefor irri-gating purposes, the stem of which adjustably engages asupporting spider which may beV removably mounted in an opening orchannel through .which Vmaterials are to flow, whereby the valve may beopened to -any desired extent `or entirely removed from the channel wayVof the said materials for offering no obstructions therein, or may beproperly held in said channel' way and tightly seatedA for comy pletelycutting off allk flow of materials.

VIn the accompanying drawing forming'a 'part o-f this specication:

to a greater or less Adegree orv entirely checked, 0r the valve maybeentirely removed when the full flow of vmaterials is desired, whereby noobstruction whatever will liquids, whereby its-flow may bef permittedl vthen be offered to tlierfpass'age of 'said mate l rials. A valveof thisliind is found especially useful in connection withY irrigating systemswhere it can be mounted or other- Wise secured in stand' pipes or uponthe end, of any kind ofpiping for regulatingtlie distribution of water'upon the ground.

Inthe accompanying drawing, a preferred form of the valve mechanism hasbeen disclosed and the details'and features ofthe scribed, referencebeing had thereto. In'the ysaid drawing, 5 indicates an attaching memberor `ring having a central opening at 6 for the passage of liquids orother materials to be controlled. The member 5 may be se-" cured withinor upon a stand pipe or a duct of any kind, in anys'uitable'manner, orsaid member may be provided with an attachingk edge portion y7, havingan outer ring and a thus formed in said member 5, and cement applied onthe end of a pipe andeXtending tions for firmly securingthe'fmember 5 inPlace. C l 1 Projecting from the member 5, a short distance back fromtheedgeisl a flange 8 eX `tending entirely around the opening 6,thefouter edge'of :said flange forminga valve seat`9. Theedge of themember 5`whi`cli veXtendsinside the Vflange forms a ledge or support 10for`the cross bar or spider which carries the valve proper. 'Adapted toen-y gage. said ledge and offer proper support for the valve' and itsstem is a frame' or Vspider 11. j The saidY spider is usually made withthree Vbar portionswhich radiate fromk y *u central `hub 12, the outerends of said bars" orispider arms being Vshaped at 13 to fit upon Ythesaid ledge 10 and withinthe {iange 8, the

length of the armsorbars of the spider 4be- "invention willnow'be'morespecically de? series of, connecting partitions joiningthe."V ring .with the body portion ofthe member 5. Cement receivingapertures or recessesare vinto said apertures form yanchoring,pr'ojecingsuch as to preventfthe spider from slip-V Y ping olfthefledgelO. Thelcentral portion of the spider is usually Vdepressed belowvv ltheVmember 5 tolfac'ilitat'e a proper seating of y the valve plate, whensaid valve plate is formed to properly engage the ,valve seat, l,andalso to voffer as littleobstruction aspos-v`r sible Vto the flow ofmaterials through the opening 6 when the spider is 1n place.

The said spider 11 is removably held upon the ledge 10 by inwardlyextending angular projections 14 upon the inner surface of the flange 8,Awhich projections forni sockets or recesses at 15 for receiving theyends of the spider arms. The ends of the spider arms may be turned inthe sockets 15, by twisting the spider when the valve is opened andelevated by its stem sufficiently to reachthe spider arms with thengers. A twist of the spider in the oppositey direction will of vcoursealso loosen the said arms ends and peryend of the latch 27, which isusually bent wire, forms a handle28 lwhich may be used to turn thedevice back and forth for locking or unlocking the spider.

- The hub 12 of the spider is provided with a threaded aperture adaptedto receive the threaded portion of a valve stem 16 which carries thevalve plate 17. A washer 18 is secured to the inner reduced end of thevalve stem 16 by a pin 19, so that the valve stem is limited in itsupward movement thereby and will not thereforek become separated fromthe spider. The valve stem 16 is also usually provided with an annularprojection 20 against which the valve plate 17 fits. kThe said valveplate 17 is provided with a central opening 21 adapted to fit snuglyupon the valve stem16 and any suitable packing kmaterial maybeinterposed between the walls of said opening and thesaid stem16 toprevent leakage. A pin 23 holds the plate snuglyL against the annularprojection 20.

VVhilethe valve plate 17 may be of any desired shape, it is preferablymade with the central part curved inwardly and considerably depressedbelow the outer edge portions f which engages the valve seat as will bereadily understood by reference to Fig. 1. of the drawing. Theperipheralfedge ofthe valve plate 17 is preferably cast or formed withan inwardly facing channel or groove 24 usually `made wider than theyvalve seatand adaptedk to carry packing Vmaterial 25.

- When the said packing materialis tightly will be readily understoodwith reference to Fig. 1. The depressed portion of the valve plate 17also accommodates a handle bar 26 which is attached to the end of thevalve stem so that said handle does not project beyond the edges of thevalve plate. y ,j

It will-be evident that minor changesin the `shape and detail featuresof the device may be made without departing from the spirit of theinvention and that a supportingmemberor bar having anydesire'd numberofarms may be employed, a corresponding number of sockets 15 beingusuallyprovided. The said sockets alford what might be termed a bayonetjoint connection for the spider which can thus be readily secured inposition or removed therefrom.

It will be evident that by turning the screw stem 16 of` thevalve, thatthe .valve may be unseated to a greater or a less degree according tothe amount ofwater that-,it may be desiredto have How from a pipe orduct. By openingthe valve sufliciently` to disengage and remove thespider arms froru the sockets 15, it will be understood that the entirevalve and spider may be removed and laid aside for permitting anunobstructed flow of water from the pipe or outlet to its full capacity.

The projections for holdingthe spider 11 in place may be varied in shapewithin the spirit of the invention. Thus as shown in Fig. 4, of thedrawing, projections 30 may be used, which are in effect, merelyinwardly l adapted to drop behind the lug 30 at the opposite end thereoffrom the end which is engagedby the lug 3 1, asclearly shown in Fig. 4,preventing the turning of the spider. in the opposite direction. n

The latch 32 has an operating end 4portion 33 which. engages a stop pin34 as shown in kFigs. 4and 5.A The latching fends ofthe device will thusnot yfall belowffthe point where fit will engage the lug 30. Therefectofthe latch 32is substantiallyv the sameas,v

the yeffect of the latch 27 and makes it possible to lock the spiderwith a straight projection 30l instead of theishoulder` projection 14.It is evident that the minor details of the invention m-ay be alteredwithout de-f.-

parting from the spirit of the invention,

, What is claimed is y 1. A valve mechanismcomprising `a member khavingavalve seat thereon and an inwardlyprojecting support having sockets,

afsupporting member having arms adapted to engage said sockets with abayonet Ajoint connection whereby the member may be readily put in placeor removed, a valve stem having a threaded engagement with said member,a valve plate carried thereby and a latch on said support adapted tolock the same against disengagement from said sockets.

2. A valve mechanism comprising a member having a valve seat thereon anda central opening for the passage of materials, a removable spidermounted in said opening, a valve plate adjustable on the spider andhaving an edge seat engaging portion, said valve plate having curvedportions leading to said edgey seat engaging portion for insuring aproper seating of the plate and a screw valve stem for adjusting thevalve Y Copies of this patent may be obtained for my hand, in presenceing an end portion adapted to be turned be-V hind the closed end of asocket for locking y the spider in place, and a valve adjustablyAcarried by said spider.
